This site is currently struggling to handle the amount of new users. I have already upgraded the server, but it will go down regardless if half of Reddit tries to join.

However Lemmy is federated software, meaning you can interact seamlessly with communities on other instances like beehaw.org or lemmy.one. The documentation explains in more detail how this works. Use the instance list to find one where you can register. Then use the Community Browser to find interesting communities. Paste the community url into the search field to follow it.

You can help other Reddit refugees by inviting them to the same Lemmy instance where you joined. This way we can spread the load across many different servers. And users with similar interests will end up together on the same instances. Others on the same instance can also automatically see posts from all the communities that you follow.

Edit: If you moderate a large subreddit, do not link your users directly to lemmy.ml in your announcements. That way the server will only go down sooner.

is it possible to move an existing profile to a new server, like on Mastodon? or I need to create a new one and "start over"?

IMHO, selecting an instance is definitely the biggest user experience problem Lemmy has at the moment. New users who are unfamiliar with the platform are going to pick the biggest instances, and that's going to create performance problems.

We'll need to prioritize work on instance browsing. Lemmy has outgrown the experience over at join-lemmy.org. If I could wave a magic wand, instance browsing and onboarding would have a way to show instance capacity / performance, a way to categorize and filter instances, and a way to recommend instances based upon interests. That would probably help to spread people out more evenly.

I applied for a few other instances but this one came through first. Your downfall is being too good compared to the competition.

I'm a noob. I created an account on beehaw and on lemmy.ml. That's because I see communities on one instance that I'm interested in and a different community on another instance. So if there's a technology community on both, how do I get to see all the technology posts without having to have two accounts?

This is really confusing for noobs like me. I'd just like to see one community to technology, one for Science, one for nintendo etc. I don't care it it's spread out amongst different servers to divvy up the load, but from the user side, it needs to be seamlessly integrated.

I'm still learning how all this works though. But I don't know how many folks that are more casual than me will be willing to figure it out. I hope they do though! It'll be worth it to leave reddit in the rearview mirror!

Edit: lawdy, I just figured it out. Local vs all on the communities list. It was right in front of my face. good grief!

well, what can be done to help with upgrades to this server? what does that entail?

[–] nutomic@lemmy.ml 16 points 1 year ago (7 children)

This site is hosted on a VPS from ovh.com. I upgraded it from 4 vCPU to 8.

Is there anyway to scale an instance by adding more nodes? Not be adding additional instances, but more of a distributed load balancing for a given instance? What about migrating communities to a different hardware instance? What scaling challenges does Lemmy face that something like Mastondon doesn't?

I'm sure there are many folks (myself included) who have technical resources that are not community builders. I'm sure if there if there is a way to spread the load, enough folks want this to succeed to make it work.

[–] Two9A@lemmy.ml 14 points 1 year ago

This comment further down states that the main issue is with the heavy JOIN-laden SQL queries that build the pages; the queries get long enough that pages time out.

Load-balanced frontends for lemmy.ml would hit the same backend/DB, as I understand it, so spinning up a frontend won't necessarily help with the load. What's needed is someone who knows pgsql optimization, and that's not me. (I might be able to help if it were MySQL...)

[–] Gecko@feddit.de 15 points 1 year ago

You might wanna consider temporarily closing sign-up requests on lemmy.ml similarly to how mastodon.social did it during its large influx. Making a sign-up request and just receiving an infinite loading icon is a very frustrating experience.

Similarly, you want to make it as easy as possible to financially contribute to lemmy, even if it means using proprietary platforms like Patreon.

Overall, the current Reddit API change is probably one of the largest opportunities for lemmy right now, so smoothing over the user experience as fast as possible in the coming days will be of atmost importance if we want lemmy to become a viable Reddit alternative...

How/which URL should we link to then? Now is the best time to get users to switch to Lemmy so we need to make it as newbie friendly as possible. Already the application process has put off some people (I do like that bit though, keeps away the low effort folks). Thanks.

[–] nutomic@lemmy.ml 14 points 1 year ago (2 children)

The one which is most relevant to the topic. So slrpnk.net if its an environmentalist subreddit, or feddit.it if its Italian. There are also a number of small general purpose instances around. I won't link anything here or else everyone would link to the same instance and it would also go down.

I would be happy to use another instance but my account is on this one. Is there a way to migrate an account, or perhaps "link" accounts on multiple instances somehow?

Hi, as one of the new people, is there a way to transfer to another instance or would I have to create a new account there?

If this is the Mastodon moment, ho boy. Don't envy the sysadmins.

[–] tmpod 14 points 1 year ago (1 children)

I know I'm being a bit pushy at this point, but distributing instance load can be helped in some part by merging this PR and deploying the latest changes (including more languages and recommended instances as well) :)

I know it probably won't be fun for you hosting, but this makes me happy! Hopefully Lemmy will grow a lot!

[–] nathanpc@lemmy.ml 14 points 1 year ago (1 children)

Saldy it's very common to have this influx towards the "main server" as people that are not used to the federated aspect come to the platform.

Either way, it would be interesting to collect this information and later post some metrics about the exodus from Reddit, kind of like how Fosstodon and other Mastodon instances did when Twitter had their issues.

Are there any published guidelines on the server requirements for an instance? I have my own instance running, seems to be working fine. But I'm reluctant to open it publically without an idea of if I'm setting myself up for failure or not.

Related, is there a way to entirely disable image uploads to my instance? I'm ok with it being a "reader" instance, but don't want to be hosting content directly.

[–] kosmo@satl.ink 14 points 1 year ago (2 children)

The backend especially is not too demanding (thanks to using a compiled binary via Rust). The database demands probably scale, but postgres scaling is relatively well understood. I think right now the least scalable parts look like the frontend node and websocket stuff, but that can be improved. I'm not sure how I feel about Activity Pub protocol wise, it feels pretty chatty, so transit scalability might be something else to consider.

[–] nutomic@lemmy.ml 15 points 1 year ago

We are currently removing websocket and switching to http, so that should be much better soon. Load from the frontend and Rust backend are both pretty low for now.

lemmy.ml should be a roundrobin dns that sends you to a random instance in the pool. Or else you will re-centralize lemmy and curmble under the IT bill.

Soo, stupid question maybe but how does federation work with your own instance?

I've set up a solo instance using ansible and subscribed to !lemmy@lemmy.ml. If I wanted my ALL page populated with posts from other lemmy.ml communities, would I have to subscribe to each individually? Or does my instance fetch lemmy.ml's Local eventually?

I've confirmed that federation is working using the method described in lemmy's docs and lemmy.ml (+ a few other instances) is listed under "Allowed instances" in my admin panel.

I'm going to setup a Lemmy node. I'm not on lemmy.ml anyway, but I want this platform to r0ck!

I'll lean it up ASAP!
